Tri-City, with the suburban area, like other Polish urban centres with metropolitan aspirations, has real chances for becoming metropolitan area of European importance. According to some European concepts, Tri-City is recognized as a member of the group of European metropolises and regarded as a link in the zone of high dynamic development in the Baltic Sea Region. The main problem for the functional efficiency of Tri-City agglomeration is cooperation and competition between cities and municipalities. The lack of common activities can be the reason of efforts and effects to squander in the field of spatial planning, programming of regional development and functioning of the whole settlement system of the metropolitan area. Pursuing the integration of Gdansk, Gdynia and Sopot and thus creating an integrated metropolitan space of the highest ability to compete in the global economy, is a real challenge for the Tri-City.
Territorial entitles and thus has influenced relations between them. In particular, these changes influenced the relations between the metropolis and its hinterland. Contemporary metropolis became a concentration of innovative activities that led to development of flows within world cities network. As a result its ties with regional surrounding, that offers mainly "simple" resources, has became relatively weaker. The article demonstrates these new processes by the empirical research of three Polish metropolises: Warsaw, Poznan and so called Triple-city (Gdansk-Gdynia-Sopot).
Identification and delimitation of metropolitan areas, as well as measuring their actual metropolitan potential, are complex research problems. They become even more complicated in the case of a metropolis shaped around a polycentric core, consisting of cities which rank similarly in the national or transnational urban network. The paper is an attempt to identify and analyze the crucial problems of internal integration within the Tri-City metropolitan area which significantly hamper the metropolitan discourse and undermine the cooperation indispensible for metropolitan development.
The paper discusses selected tools within Cohesion Policy that stimulate cooperation between cities. Subject to analysis are two programmes from 2004?2006: INTERRREG and URBACT. In the case of INTERREG programmes, the analysis pertains to the largest Polish cities (31 most populous cities and the Silesian and Tri-City conurbations), while in the case of URBACT, all the cities that were beneficiaries of the programme were taken into account. The results of the projects are usually of the soft type and involve transfer of good practices, building institutional capacity, and human capital. In this respect, the results of the analyzed projects should be considered at least satisfactory, although the number and scale of the completed projects does not allow for clear and measurable effects to be perceptible in a country-wide perspective.
